ALVIN F. NYE, OF ROCHESTER, NET/V YORK, ASSIGNOR Ti FLLBAO TION, OFROCHESTER, NEXV YORK, A oonrona CORT 3N OF WINDOW SCREEN.

Application filed May 14, 1921, Serial This invention has to do withwindow screens and relates more particularly to the construction ofbinding strips or railsfor the same and the means for, connecting thelatter to the screen material, the chief object of the invention beingto provide a simple, practical and inexpensive construction affording astrong and durable rail with an efficient and convenient means forsecurely attaching To these and other ends the invention consistscertain improvements and combinations of parts, all as will behereinafter more fully described, the novel features being pointed outin the claims at the end of the specification.

22 of Figure 1 showing the construction of the binding strip or rail andthe connection of the latter with the screen material.

Similar reference characters throughout the several views indicate thesame parts.

The present invention provides an advantageous binding strip or rail fora window screen, in the present embodiment showing the same as appliedto a window screen of the type employing a flexible wire cloth ormosquito netting wound on, a spring roller journalled in the windowcasing. Referring to Figure 1 of the drawings, which illustrates such anapplication of the invention, there is shown at 5 a window casing with asill 6, 7 indicating the stops or guide strips for the outer windowsash. Fixed on the latter are guides 8 preferably in the form of sheetmetal channel members having inner and outer flanges 9 and 10respectively between which the screen material slides. The screen iswound. on a spring actuated roller 11 journalled at its ends in bearings12 on the casing, these parts being preferably located in a housing 13at the top of the casing, the roller turning to wind or unwind thescreen material as the latter is raised or lowered by means of a bindingstrip or bottom rail secured to its lower end.

The wire cloth or netting of which such screens are generally made isrelatively still, and as it must be maintained in close fittingengagement with its guides on the window casing to prevent openingsthrough which insects might pass, the screen material offers N0. [169503 Renewed April 1, a frictional resistance inst sliding movement andrequires a substantial binding strip or rail at its lower endv carryingthe l dies or other means by which he screen is moved, which rail. mustbe cap of close engage ment throughout len 'tli w th the window shelfand moreover must be securely connect ed with the screen material toprevent the latter from unraveling at its edge or otherwise becomingtorn or discon ectec from the rail. To this end there is preierablyprovided a rail indicated generally at 15 as formed from a single stripof sheet metal, of substantially channel shape, having an intermediateflat portion adapted for close engagement with the window sill, with anularly extending flanges 17 and 18 at its si The flanges extendsubstantially parallel 1th each other and are preferably corrugated asl9 adjacent the intermediate portion to provide a somewhat resilie tconnection to absorb the shock of impact against the window sill, and tostrengthen and s'tiit'en the same a5; st lateral binding. As shown inthe drawing, the inner flange 17 preferably has its upper or marginalportion curved toward the other flange 18 and bent sharply upon itselfas at 20 to provide a projecting ri ge portion, the flange beingcontinued beyond such portion as at 21 for engagement with the otherflange and these engaging portions may be securely fastened together ifdesired, in any suitable manner. The other flange 18 has its marginalportion curved as at 22 to closely embrace the sides of the ridgeportion 20 and its edge is turned inwardly of the rail as at 23. Theseembracing marginal portions of the flanges are preferably so formed asto leave a slight space therebetween and the edge 23 is externallyexposed as shown in Figure 2.

The screen material has its lower end inserted between the embracingportions of the flanges, being bent twice upon itself to extend aroundor embrace the ridge portion 20 vided with handles 24 for moving thesame.

As apparent from the construction shown and described, the rail issimple and practical in character, being preferably formed from a singlestrip of sheet metal which is readily rolled into shape. The rail hassufficient width in cooperation with the screen guides to maintain it inproper alignment uring movement and is adapted to closely engage awindow sill and close the window tightly and the character ofconstruction adopted afi'ords a strong and-durable rail capable ofwithstanding any force necessary to be applied. Combined with thisadvantageous construction of the rail is the eflective connectiondescribed between the latter and the screen material whereby thematerial is readily attached during assembly and securely engaged andheld by the rail at all points over the width of the material and for asuflicient distance from its end as to obviate any danger of its tearingor pulling away from the rail. In addition to these practicaladvantages, the rail and its method of connection with the screenpresent a neat and attractive appearance.

I claim as my invention:

1. A binding rail for a window screen comprising an integrally formedsubstantially channel shaped bottom rail having its intermediate portionat the bottom for contact with the window sill and upwardly extendingflanges at'the sides thereof, an upper portion on one of said flangesbent downwardly on itself to form an upwardly projecting a ridge and adownturned edge for attachment to the other flange, and an upper portionon the other of said flanges bent over and closely embracing said ridgewith a downwardly extending edge adapted to hold a screen materialbetween said ridge and said embracing portion.

2. A binding rail for a window screen comprising an integrally formedsubstantially channel shaped rail having its intermediate portiondisposed for contact with the window ca sing with side flanges extendingangularly therefrom and provided with a plurality of corrugationsaffording resilient connection with said intermediate rail portion, aprojecting ridge portion on one of said flanges, and a marginal portionon the other of said flanges closely embracing the sides of said ridgeportion with an externally disposed edge portion and adapted to hold ascreen material between said ridge and said embracing portion.

3. A binding rail for a rolling window Screen formed integrally from asingle sheet metal strip shaped to present an intermediate portion forengagement with a window casing with angularly extending flanges at thesides thereof, one of said flanges having its margin curved back uponitself to provide a ridge portion and to engage with said other flange.said other flange having its margin curved to closely embrace said ridgeportion with its edge portion extending inwardly of the rail, and beingadapted to retain a screen material between said curved margin and saidridge portion, and'a handle on said rail.
